Title: A conceptual model of cumulative environmental effects of agricultural land
Author: Harry Spaling and Barry Smit
Agriculture, Ecosystems & Environment, Volume 53, Issue 2, April 1995, Pages 99-108
Drainage modifies flow regimes and contributes a mechanism for the spatial movement of water and contaminants from one location to another. Potential cumulative effects of drainage include the repeated addition of drain water to receiving streams (time crowding), the systematic gathering of contaminants at higher concentrations relative to the source (spatial crowding) and their transport from agro ecosystems to aquatic ecosystems downstream (cross-boundary movement), and the severing of natural areas resulting in altered landscape structure and functioning (spatial fragmentation). The model hypothesizes that, as drainage density increases, changes in environmental components or processes manifest themselves as cumulative effects, and that these effects accumulate at broader temporal and spatial scales.
